I already have a sigma 17-70 f/2.8-4.5 and I've been wondering if I should get a 17-40 to go onto my 30D.
It would add to my 24-105 f/4 and my 70-200 f/2.8
I shoot a lot of sports and have two crop bodies. one would wear the 70-200 while the 30D would wear a wide lens. Is the 17-40 worth it over the 17-70?
I have no plans to go to FF anytime soon
